* Bundles are rendered as a single {@link HeaderItem}, rather than several, and require only one
* HTTP request to download, which can greatly reduce the number HTTP requests needed to get all
* resources for a page. Resources need to be registered in {@link ResourceBundles} under
* {@link Application#getResourceBundles()}.
